Hey all,

This isn't really a DIY thing but I was wondering whether anyone thought there could be a chance of one of these mini flashes working as a strobe trigger (if it fits in a housing obviously)?

To clarify, I'm not planning on actually doing this, just thinking it could be a potential cheap "emergency backup" option for if my TRT trigger breaks on a trip 😁

Hmm I might not be the knowledgeable one when it comes to those flashy things, but Olympus FL-LM3, which is also a "normal" flash, works fine. I think the major issue with the Godox will be fitting it inside the housing - FL-LM3 only fits because Nauticam designed the housing with the necessary space.

If it fits the housing it will work, turned down to minimum power is fine.  Sony may be an exception ?  this flash only uses the center contact and ground to trigger and is fully manual.  I expect it has significantly more light output than an LED trigger and should have no problem triggering any strobes assuming it points at the fibre optic ports.

It's not an issue with the SeaFrogs flash trigger, which is a similar, albeit even more compact and fixed-power flash (not LED).

There are a zillion little strobes on ali express that might work, they will be much stronger than any LED trigger.

Trying to get the output aligned to the window for the fiber might be the biggest issue.

 Yes, Sony would be the exception. That little strobe does look like something that will work if it fits. 

@Yorkie88 It appears this works with the Sony A6700 in a Nauticam housing. One of our members @boduoguo has a picture of his set up in a thread about the Sony A6700.

There isn't quite as much space in the A7RV compared to the 6700 but I found a smaller looking flash, the MedaLight F1S, so I ordered one to try out - will report back if it fits!

It fits easily in the NA-A7RV housing, it's not much bigger than the TRT trigger.

It doesn't line up with the holes to trigger it straight away, but just putting my finger in front of it bounced it off enough to trigger my MF-2 so I'll see if I can 3d print something and stick foil to it - which is pretty much what my seafrogs housing seems to use to bounce the light to the fibre ports.

There's a slant at the front of the flash which could be a good place to put something simple on.

It's never going to do anything fancy but it could be a cheap backup option at around $55 AUD.
